Great Mexican food with lots of options. Their sauces are delicious and salsas are spicy and flavorful. Might just be the best I’ve had in Boulder -

Great Mexican food. My family and I have been coming here for years. Margs are great, I usually get the Coin and my dad gets the gold rush. My go to order is the costilla ribs or the Efrain burrito. Have to get something with green chili, it has the right amount of heat -

Visited this establishment on a recent trip to Boulder and boy, were we pleasantly surprised! Some of the best authentic Mexican food I’ve ever had. After reading the Google reviews, we knew we were in for a good experience, but one never knows till they try it for themselves. Food was out of this world! Margaritas are also outstanding. During our entire trip to Colorado, this was by far our most enjoyable and best value meal. I highly recommend you give them a try if you are visiting Boulder or if you live in the area and have never been, I promise you won’t be disappointed! -

EFRAIN’S MEXICAN RESTAURANT & CANTINA
Efrain's II - 1630 N. 63rd St., Boulder, 303-440-4045
Our favorite dish at Efrain’s is a little something called blue corn enchiladas with chicken and a side of green chile to pour over the top, to give it a spicy kick. Oh, and a margarita or a Negra Modelo with lime. Sorry, just drooled a little bit on the keyboard. Efrain’s has been a Boulder County institution for more than two decades, delivering authentic northern Mexican cuisine from the state of Chihuahua. It is a recipe for a satisfying south-of-the-border experience. Olé.
Ever tried the Mexican Ribs at Efrain’s? Sweet mother of Zeus, they are spicy. We’re not talking about your classic barbecue ribs, these babies are soaked for, like, days in green chile. And this may well be the best, hottest green chile this side of Taos. Makes the margaritas go down a lot quicker, let’s put it that way. The nice thing about this East County restaurant is that there are three locations, so no matter what ‘L’ town you live in, you’ll never be far from delicious Mexican food. But when ordering, keep an eye on the handy spicelevel scale that appears next to each dish on the menu. Your tongue will thank you later.

Efrain's Wins First Place - Best Mexican Food 2011
September 23, 2011
2011 Boulder County Peoples Choice Awards
Ask Efrain what style he specializes in and he says laughingly, “REAL traditional Mexican food! Everything is fresh. We start cooking in the kitchen at 6 a.m., every day. I learned cooking from my mom; she is the best cook in the world, I think.” The original Efrain’s in Lafayette opened over two decades ago. Efrain had worked in other relatives restaurants, and pretty soon he decided that he wanted to start his own. Since then, Efrain’s has developed a loyal fan base who keep coming back for the chimichangas, fajitas and the chili verde. Efrain opened a second location in Boulder twelve years ago, followed by the Longmont Efrain's in 2005. Efrain's has won Boulder County's coveted People's Choice Award for the best Mexican food every year since the awards began in 2009. Thank you Colorado!!!!

Efrain's

Bite Into boulder
The combo plate was the perfect option to first-timers like myself to sample a few different items. And it was so huge, I took about half of it home for lunch the next day. Efrain’s is hands down one of the best deals in town, absolutely the best Mexican I’ve had in the area, and is so off the beaten path it is a great change of scenery. The only draw back to this is it is about a ten minute drive, which is unfortunate if you’d like to sample a margarita, or two. Nevertheless, it is absolutely, 100% worth the drive and possible wait, for hands-down the best Mexican food in town :)
Efrain’s

After hearing my friends rave about Efrain’s for weeks, I finally persuaded them to bring me to their favorite, local spot for quick and cheap eats. Better yet, I persuaded them to drive so I could sample my first Efrain’s margarita, and damn was I sure we made that arrangement.
I decided to dive right in and order a marg from the bar while we waited for our table: rocks, no salt. As I watched the bartender pouring this delicious concoction, I kept waiting for her to lay off the tequila, but it kept coming until about right below my thumb. For five bucks, this strong and icy beverage was the perfect way to pass the time while waiting the ten minutes for our table. Yet by the time we sat down, I was already feeling the tequila and ready for the chips I’d been eyeing since we walked in.
Immediately upon being seated, we dove into the chips and salsa, which were waiting for us at our table, accompanied by a side of guac which we ordered in addition. There was nothing canned or mass-produced about any aspect of this starter: it was the real deal. The salsa was hot, yet paired with the fresh guac, was the perfect combo of spicy and cool. Though the salsa was a little soupy for my liking, the guac was hearty enough to make up for it, and I enjoyed dunking one chip in both dips.
My date (Kate) and I both opted for Efrain’s combo platter for our main course. This dish featured the choice of three different tasting options. For ten bucks, this colossal dish was more than satisfying and a great way to sample a few different items. Out of the choice of about eight options, I went with a chicken enchilada, chicken taco and rice and beans. It would be a struggle to find something bad to say about any of them.
First off, the enchilada. I could barely focus on the filling inside the tortilla because the sauce and melted cheese was so killer. The red sauce that the enchilada was swimming in contained the perfect amount of spice and flavor without overpowering the dish, but I wished the sauce was smothered over the entire plate, not just the enchilada. Though I’m still debating whether or not the enchilada actually had chicken in it, it didn’t even matter.
For the chicken taco, it was the presentation that really made it stand out. After stuffing (and I mean STUFFING) a tortilla with shredded chicken, shredded lettuce, and cheese, they then grilled the entire taco to make the tortilla crispy. I had never heard of a taco being prepared this way before, but it really added a nice touch to an otherwise standard dish. Though the chicken inside was a little dry, a little of the red enchilada sauce did the trick.
Last, but not least, the rice and beans. Normally, I would never order such an average dish when every other item on the menu was popping out at me. Yet I took Kate’s advice, and ordered her absolutely favorite dish of all time, which she swore Efrain’s did it right. One bite in, and I was glad I took the advice. The rice and beans were out of this world. The beans were flavorful yet not mushy, rice was cooked perfectly, and all was topped with a layer of melted cheese, which again I mixed with the enchilada sauce. I think it was the melted cheese that really put it over the edge, but no matter what I order at Efrain’s from now on, I will absolutely be sure to order the rice and beans as a side.
The combo plate was the perfect option to first-timers like myself to sample a few different items. And it was so huge, I took about half of it home for lunch the next day. Efrain’s is hands down one of the best deals in town, absolutely the best Mexican I’ve had in the area, and is so off the beaten path it is a great change of scenery. The only draw back to this is it is about a ten minute drive, which is unfortunate if you’d like to sample a margarita, or two. Nevertheless, it is absolutely, 100% worth the drive and possible wait, for hands-down the best Mexican food in town (but what do I know, I’m from Boston).

Best Mexican food in Town!

No question! And it's a family owned authentic restaurant, not a posuer place like some around town. Go for the beef enchilada or The Efrain. Green chile is not to be missed.

Some of Colorado's Best Green Chile
February 9, 2011
City Search
Efrain's has a large menu of traditional mexican and southwestern dishes. But if you're looking for authentic green chile, this is the place to get it on the front range. None of this anemic, gelatinous goo the other places dribble over their fare. This is the real deal, with chunks of lean pork in a flavorful, roasted green chile sauce packing plenty of heat. Put out the fire with fresh made tortillas and perfectly mixed margueritas.
